Day One/Week One numbers are always going to cast Blu-Ray in an overly favorable ligbt, because the extreme videophiles who rush out to buy a new release as soon as it comes out are the same people who are willing to shell out big money for HD equipment.
A better evaluation would be comparing sales of Blu-Ray against DVD over, say, six months to a year. That's a major reason why Blu-Ray sales have been so slow when new releases weren't appearing - all the videophiles buy them right away at release.
I'm sure the Blu-Ray group will crow about the amazing revenue for week one sales of Iron Man... but that's not really going to tell us much one way or another.
PS: Tracking "market share" is a great way to disguise actual performance.
